Some tips from Maine. But I'm leery of predicting anything. What works is honesty, not fear. And you can still help:
Out-of-state volunteers can make phone-calls from home, while there are organized phone-banks going on across the country. East Coast volunteers can take a day (or weekend trip) to Maine and find a carpool through an online feature that pairs up people in your area. And you can donate money or airline miles to send volunteers for a week at Travel for Change. Or you can give to the California Young Democrats, who will be helping the last-minute college campus push by getting plane tickets for volunteers who will be on the ground during the last four days.
